Kobayashi and Ichikawa (2016) recently reported that briefly presented images with dangerous impressions were detected with higher accuracy than images with safe impressions and concluded that the emotion evoked by such images improves temporal resolution of visual perception. In this study, we assessed confounding effects of the color saturations of the images used in their study. While attempting to replicate their results, we found the opposite results—that is, images with safe impressions were detected with higher accuracy than those with dangerous impressions. This likely reflected an observed correlation between color saturations and detection thresholds. To confirm the effects of color saturations, in subsequent experiments, we independently examined the effects of emotion and of color characteristics. We concluded that the previously reported increased temporal resolution was due to the confounding effect of color saturation, and not by the evoked emotion.
